It was reported during a knee arthroscopy the procedure went very normal and the pump functioned properly without overpressure.
The pump was at the same level as the operative site.
All readings were normal and there was no excessive fluid noticed from the knee.
However after the procedure and before closing it was noticed the patients calf was extremely swollen and very hard due to compartment syndrome.
A fasciotomy was performed with a four to five inch incision which released the pressure and pure saline came out.
This made an immediate relief to the calf area and it soon went back to the same size as the calf on the other leg.
The doctor closed up the incision and is confident the problem is resolved.
The doctor believes the patient had a tear in the knee capsule which lead to the fluid leaking down to the calf.
Additional information obtained 05/21/2020: the procedure was on the patient's right leg.
The pump used with the tubing was ar-6480, serial number (b)(4).
Both the pump and tubing will be returned for evaluation.
